False aligation of sexual harassment from a girl.

I am a collage student, and a girl files a false statement of sexual harassment against me and she has two faculties in her favor who have some personal greges from me and they called me and mentally harassed me i have a recording of 1 and half hour in which the faculty has mentally harrassed me and my one collague. They doesn't have any proof against me but still they are having the privilage of being faculty and are mentally harassing me. Slowly i am being depressed because she has taken the case to my family and she has given false statements to my parents. Main thing is that the teacher is forcing the girl to file a false case of sexual harassment against me, and because she is a faculty she has taken HOD and DEAN of my department in her side and now i am in no condition to think what should i do ? Please help me !
